Melt the butter gently in a pan, and when completely melted, remove from heat.

Stir in the condensed milk until completely mixed, and stir in chocolate and coconut, again until completely mixed.

Stir in the crushed biscuits, about a quarter at a time. This makes it easier. Also, keep an eye on the mixture. If it is too stiff, don't add all of the biscuits, if it's too loose, add a couple more. You should be able to roll it into balls.

Roll into balls, makes around 24 bitesize balls but you can make them any size you like. Roll in the extra coconut and leave to set.
